This is also definitive evidence that our government’s policies discouraging domestic cryptographic research have backfired, since now some Chinese university researchers are ahead of our own NSA. (*)

(*) Footnote: I believe this to be true because if this were an attack the NSA were aware of, they’d have released a SHA-2, the same way they replaced SHA with SHA-1.

(Change notes: previous version of this post said “they’d be working towards” rather than “they’d have released”, which is clearly an absurd thing to say. Also, it said “would be aware” rather than “were aware”, and “it aided the creation of a SHA-1” rather than “they replaced SHA with SHA-1”; these changes were made for clarity.)
